Temperature-dependent electronic structure of EuO films

Abstract We present calculations for the temperature-dependent band structure of ferromagnetic EuO films based on a parametrization of the d–f model Hamiltonian using results of first-principles TB-LMTO band structure calculations. The combination of first-principles calculation and many-body model calculation enables us to determine the temperature-dependent bandstructure of up to 20-layer EuO-films over the entire temperature range.
